2.1.2 Precipitation of aluminum hydroxides and oxyhydroxides. The mineral bauxite, which is a mixed hydroxide of iron and aluminum, is the raw material at the origin of the industrial chemistry of aluminum compounds. Bauxite is transformed into sodium-contaminated gibbsite in the so-called Bayer process (32,33).
